Environmental Harm (1)
MLI Industrials Current as of April 2026

This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.

Environmental Damage
Since Mar 19, 2026

ViolationTracker documents $2.65 million in penalties across 59 records for Mueller Industries since 2000 for environmental violations. Mueller Brass, a subsidiary, agreed to pay approximately $60,000 in penalties to Michigan EGLE for violations at its Port Huron facility after a state air monitoring station recorded elevated lead levels and identified the plant as a probable source. Violations included failure to properly maintain particulate emission control equipment, leading local health officials to offer lead blood testing to residents in the surrounding neighborhood. Mueller Industries is designated as a potentially responsible party at Superfund CERCLA sites related to its copper products manufacturing, reflecting legacy contamination from its industrial operations.

Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.

This information is provided for educational and transparency purposes only and should not be relied upon as investment advice. Data is drawn from independent watchdogs, NGOs, government registries, and Ethical Capital's ongoing research — see Research Sources for the full list.
